Answer:

31.1 meters long

Step-by-step explanation:

Since there are 22 pieces that are 1.3 meters long, you'd have to multiply them together.

22*1.3= 28.6 meters

Once you get that, add the longer piece of slate (2.5 meters) to get the total length.

28.6+2.5 = 31.1 meters

Answer: 31.1 meters

Step-by-step explanation:

First multiply the number of pieces of slate that he uses by how long they are, so: 22 x 1.3 = 28.6. Then, add the remaining one long piece of slate that he uses, so: 28.6 + 2.5 =31.1. Don't forget to answer using the measurement they gave you. So, answer is 31.3 meters
